Swing, a game equipment, is made by tying a long rope to a frame and hanging a paddle board below. People swing back and forth along with the paddle board. Swing is a kind of sport created by ethnic minorities in northern China in ancient times. It was introduced to the Central Plains during the Spring and Autumn Period. Due to its simple equipment and easy learning, it was deeply loved by people and soon became popular in various places. After the Han Dynasty, swings gradually became a folk custom activity carried out during festivals such as the Qingming Festival and the Dragon Boat Festival, and have been passed down to this day.

 

 

 

A swing is a mechanical system, and it is subjected to two external forces: one is the downward gravitational force; The other one is the binding force acting at the suspension point 0, whose direction is always along the swing rope. We know that only when external forces keep doing work on the system will the swing get higher and higher. The two external forces mentioned above, the direction of their binding force is always perpendicular to the direction of the swing's movement, so they do no work. Only the work done by gravity in each back-and-forth swing of the swing is "pushing" by gravity. We know that a person's center of gravity is higher when standing than when squatting. That is to say, when swinging in the same way as mentioned above, the center of gravity of an ascending swing is higher than that of a descending one, and when swinging, a person's axis follows the swing rope. In this way, the force of gravity acting on the center of gravity affects the suspension point when the swing rises. The torque is smaller than when it descends, so the total work done by the up and down torques is positive. Since there is energy input for each round trip of the system, the swing naturally swings higher and higher. In the end, no matter which way you swing, it is all done by the external force acting on the swing system. Either swing high or maintain a certain height. However, for an external force to do work on a swing, an important condition is that the external force's push should be in harmony with the rhythm of the swing's swing. The swing of a swing has a rhythm, and so does the push of an external force. Only when the two rhythms are in harmony can the swing rise higher and higher. Meeting this condition is also called resonance. What we discussed above is the swing used in sports. In fact, we often encounter many other different types of "swings", that is, "swings". It is the core part of a typical pendulum clock: a pendulum and an escapement wheel. The lower part of the pendulum is A metal hammer A, which is connected to the suspension point by a connecting rod. Some craft pendulum clocks simply make the heavy hammer of the pendulum into a girl playing on a swing. The back-and-forth swinging of the pendulum is exactly like a girl "swinging on a swing". It's just that the girl's motivation for swinging on the swing comes from a ingeniously designed "escapement wheel". The escapement wheel B is driven clockwise by the mainspring or other power sources. The escapement fork c connected to the pendulum swings with the pendulum, allowing the escapement wheel to rotate only one tooth in each round trip of the pendulum. However, the most ingenious design of the escapement wheel and escapement fork is the shape of the teeth and the end of the escapement fork. It is to make the gear input a small amount of energy to the pendulum with the power of the escapement wheel each time it "escapes", just like someone "pushing" a swing, making the escapement wheel do work on the pendulum. Only in this way can the pendulum keep swinging; otherwise, it will stop.

 

2 Basic Introduction

Chinese name: Swing

It is used as a game tool. A long rope is tied to the frame, and a pedal board is hung below. People swing back and forth along with the pedal board.

3 Historical Origins

The origin of the swing can be traced back to several

Swing
In the ancient times 100,000 years ago. At that time, our ancestors needed to climb trees to pick wild fruits or hunt wild beasts in order to make a living. While climbing and running, they often grasped thick climbing plants and relied on the swaying of the vines to climb trees or cross gullies and streams. This was the primitive prototype of the swing. As for the swings with ropes suspended from wooden frames and footboards tied at the bottom, they already existed in northern China during the Spring and Autumn Period. In "Yiwen Leiju", there is a record that "in the northern mountains, the Rong people used swings as a pastime during the cold food festival." At that time, for the sake of sturdiness, the ropes used to tie swings were usually made of animal skins, so the characters for "swing" were all written with the radical "leather".

4 Relevant Customs

This is a custom of the Qingming Festival in ancient China. Swing, meaning to move while holding onto a leather rope. It has a very long history. It was originally called "Qianqiu", but later, to avoid taboo, it was changed to "Swing". In ancient times, swings were mostly made with tree branches as the frame and tied with colorful ribbons. Later, it gradually developed into a swing with two ropes and a step.

In ancient times, swinging on a swing was only seen around the Qingming and Hanshi Festivals, and it was only used as a game among the red men and green women in the wealthy and noble families.

5. Swing Classification

Fang Chuan

Swinging on a swing is a common recreational competition among many ethnic groups across China. According to existing literature records, it originated in the Pre-Qin period.

The "Ancient and Modern Art Picture" states: "This swing is a play of the northern mountain Rong people to learn lightness (agility)." The Shanrong were an ancient ethnic minority in the north, with their territory in today's Beijing and its surrounding areas. The swing was originally a tool for their military training. (See Volume 3 of "Popular Compilation" by Zhai Hao of the Qing Dynasty) After Duke Huan of Qi, the first of the Five Hegemons of the Spring and Autumn Period, led his troops to defeat the Shanrong, he ceded his territory to the State of Yan. As a result, the swing spread southward and gradually evolved into a game tool.

Swing in ancient times

Swinging on a swing, in the future, was mainly a game for women in the palace and boudoir or a part of traditional festival square revelry. Swinging was very popular in the palace during the reign of Emperor Wu of the Han Dynasty. In his "Swing Rhapsody in the Harem of Emperor Wu of Han", Gao Wuji of the Tang Dynasty wrote: "The swing is for a thousand autumns." Emperor Wu of Han prayed for a long life, so there were many swings in the harem. Swinging on a swing was mainly for physical fitness at that time. In the Tang Dynasty's imperial court, swinging on swings was called "semi-immortal Play". Wang Renyu of the Five Dynasties wrote in his notes "The Anecdotes of Kaiyuan and Tianbao" : "In the Tianbao Palace, during the Cold Food Festival, swings were erected, making the palace concubines laugh and play as a form of entertainment." The emperor called it a play of semi-immortals, and thus the people of the capital called it.

Water swing

"Water swings" emerged in the Song Dynasty. According to the records in books such as "Dreaming of Liang Lu" by Wu Zimu of the Southern Song Dynasty, such acrobatic performances were held not only in the Jinming Pool of Bianjing, the capital of the Northern Song Dynasty, but also in the West Lake and Qiantang River of Lin 'an, the capital of the Southern Song Dynasty. Every summer when the water swing performance was held, people from the emperor's concubines, nobles and ministers to common folk all vied to watch. Before the performance, two elaborately carved large ships were placed in the water, with tall swing frames erected at the bows. During the performance, the drumbeats on the boat were loud. The jugglers at the stern first practiced on the pole, and then the performers took turns to swing on the swings, swinging back and forth with all their might. When the swing reached the same level as the crossbeam of the swing frame, they released the rope with both hands and jumped into the air with the force of the swing's reverberation, did a somersault in the air, and then threw themselves into the water. Because the performers' postures vary, it looks thrilling, elegant and ever-changing. The "water swing" is similar to modern diving and represents a new development of acrobatics in the Song Dynasty. It holds an important position in the history of Chinese acrobatics and has had a considerable influence on later generations.

After the Tang and Song Dynasties, the custom of swinging on swings spread throughout the country, reaching an unprecedented scale.

Sharpen the autumn wind wheel swing

In the ethnic minority areas of southwest China, there are also popular swing forms such as the "grinding autumn" and "windmill swing".

Grinding autumn can be divided into two types: one is called rotating grinding autumn, and the other is called grinding Dan autumn. In the middle of the "Rotating Mill Autumn", there is a pillar with an axle on top. Four ropes are tied to it, and at the end of each rope, there is a ring. Four people hold the rings and rotate and leap to form a play, resembling a grinding mill, hence the name "Rotating Mill Autumn".

The way to play with "Mo Dan Qiu" is to take a hard piece of wood that is 1 to 2 meters long and about 15 centimeters in diameter, fix it vertically on the ground, and sharpen the top to make an axis. Select another wooden pole about 10 meters long and with a diameter comparable to that of the wooden pillar. Make a concave hole in the middle and place it horizontally on top of the pillar. This way, a grinding pole is built. The number of people on both ends of the wooden pole is equal. After running a few steps on the ground with their feet, the riders quickly get on the pole or crawl on the pole head. The pole then rotates like a mill, rising and falling up and down at both ends, similar to the ups and downs of a carrying pole when carrying a load. Therefore, it is called "grinding the pole Autumn". As the wooden pole rotates and undulates, the side that lands uses its foot to push off the ground, increasing the force to make the pole bounce up. In this way, the two ends of the wooden pole alternate up and down, and the rotation never stops.

The Mo Dan Autumn is most prosperous among the Dai, Jingpo, Miao, Zhuang, Hani, Buyi and Gelao ethnic groups in regions such as Yunnan, Guizhou and Guangxi, among which the Hani ethnic group is the typical one.

The Hani people mainly polish autumn in the fifth or sixth lunar month. May is held on the day of Xu or Hai and is called the "Year of May". The festival is held on the 3rd to 5th in the middle of June and is called the "June Year". The Hani people call it the "Kuzaza" Festival. Both the "May Year" and the "June Year" are the Autumn Grinding Festival. There is a local legend about the origin of the "May Year" : In ancient times, the sun and the moon rose and fell unpredictably, harming the crops. The brother and sister, A Lang and A Chang, decided to help their fellow villagers. They cut down chestnut trees to set up a mill. The mill spun fast, carrying them up to the sun and the moon. They went to great lengths to persuade them to come and go regularly day and night. The ideal was realized, but the brother and sister were respectively baked to death and frozen to death on the sun and the moon. People evolved it into a festival to commemorate them.

The windmill swing, also known as the "car swing", "rotating swing", "rotating swing", or "spinning wheel swing", is so named because its shape is slightly similar to a spinning wheel. The structure of a windmill swing is more complex than that of a hanging swing or a grinding swing. Two wooden columns about 3 meters high are placed in the ground, about 3 meters apart. A crossbeam is placed on top of each column, and a wooden cross-shaped roller about 1 meter wide, resembling a wheel, is placed in the center of the crossbeam. There are four pairs of parallel feet each about 2 meters long on the roller. Short ropes are tied to the ends of the feet, and a wooden board is attached to the ends of the ropes, resembling a swing. When playing, four people each sit on a wooden board and make the roller rotate, moving up and down. When each person's feet touch the ground, they push off with all their might. Coupled with the force of three people sitting down and pulling down in the air, the swing rotates in a circle. When the speed is high, it looks like a large windmill spinning, which is very beautiful. In the Miao ethnic area of Qiandongnan, each seat of the windmill swing can seat two people, and four seats can seat eight people. Such a windmill swing is called "Eight-Person Autumn". Windmill swings are popular among ethnic groups such as the Miao, Achang and Lisu, with the Lisu being a typical example. Most of the Lisu people who swing on the windmill swing are women. During festivals, they come to compete in their finest clothes. During the competition, participants are divided into several groups, each consisting of four people, and they take turns to compete. The contestants sat on the swing board with their faces facing outward. At the referee's command, the swing began to spin like a spinning wheel, getting faster and faster, as if spinning a colorful ball.

Swings of all ethnic groups

Swing
Swing
Of course, it is in the ethnic minority areas of our country that there are many variations on swings.

The Korean ethnic group loves the traditional competitive game of swinging. This activity is often held during festivals and sometimes even involves competitions. During the festival, girls, dressed in brightly colored skirts, gather around the swings, competing to see who is the best. Only the selected experts can participate in the sports meeting. During the competition, a string of golden copper bells is hung on a colorful ribbon at a high altitude. The contestants swing on the swings to see who can strike the bells. The more times they strike the bells, the higher their score. The flowing long dress, the pleasant jingling of bells, and the thrilling swaying are all breathtaking.

The Gaoshan people in Taiwan call swinging "Miaomian", which means "flying to the heavens". This is the same as the traditional understanding of swings among the Han people.

The custom of swinging among the Naxi people in the northwest of Yunnan and the south of Sichuan is commonly known as the "Swing Meeting". The swing festival in the eastern part of the Naxi ethnic group is usually held from the first to the fourth day of the first lunar month every year, while in the western part it starts on the sixth day of the first lunar month and lasts for 4 to 5 days. The Qing Dynasty's "Yanyuan Zhuzhi Ci" states: "High hanging colorful frames reach the clouds and sky, celebrating the New Year together to surpass the old one." Sisters compete in their gorgeous dresses, and the young man throws the rope to swing on the swing. In the area of Baisha Village in Lijiang, brides who got married in the past often tied red strings to the armrests of swings and entertained the swings with snacks, sunflower seeds and other treats, hoping for peace and good luck. In Yongning and other places, after the "Swing Meeting", young women prepare banquets to entertain the young men who come to compete on the swings. During the meal, men smeared women's faces with smoke from a pot and chased and played with each other, believing that smearing the face was auspicious. Legend has it that during the ancient "Swing Fair", demons would come to capture beautiful women. Later, because this method was used to cover one's face and prevent being harmed by ghosts, it became another custom in the fair.

Variations of the swing

In addition to the common "hanging autumn", some ethnic groups have many variations of swings.

The swing game of the Kyrgyz people in Xinjiang is locally known as "Alatibakan Sheriqinjik". Choose a spot on the open ground and build a tripod with three pieces of wood. At another point 3 to 5 meters away, build the same frame. Then, set up a crossbeam between the two tripods, about 3 meters above the ground. Hang six "U" -shaped cowhide ropes on the crossbeam to form a swing. When playing, a man and a woman face each other. Both of them cross their feet and push against two longer cowhide ropes. They stretch out their arms to each grasp two cowhide ropes, rest their backs on the ropes, and push their feet, swinging higher and higher.

The swing swing used by the Tu people in Qinghai is on wheels. The Tu ethnic group calls the autumn wheel "Bu Ri Re", which means "rotating" or "turning the wheel". The wheel autumn is made based on local conditions and using local materials. If the column wheels of the large flatbed cart are removed, stand the cart column upright and press a heavy object on the lower wheel to fix the center of gravity. A ladder is tied to the upper wheel, and equal-length leather ropes (similar to swings) are tied to both ends of the ladder. Therefore, it is called "Wheel Autumn".

The swing played by the Uyghur people is even more unique. It is called "Shahar Di", meaning "air wheel", and is played on during spring and autumn and at weddings. A round log about 10 meters high was firmly erected on the site as a shaft. A wooden wheel was installed on top of the shaft, and two crossbeams were attached to the wheel, each tied with a rope, resembling a swing. An additional crossbar is installed at the bottom of the vertical shaft and connected to the top wooden wheel with a rope. During the game, one person stands on each side of the rope swing. Then, on both sides of the bottom crossbar, several people stand facing each other. Both sides push the crossbar at the same speed, causing the top wooden wheel to rotate. The player standing on the rope gradually rises to a higher altitude as the wheel accelerates. The faster the speed, the higher the player flies.

6 Swing Culture

Swing
Swinging on a swing can not only "cure diseases" but also "relieve boredom". The opening of the 25th chapter of "Jin Ping Mei Ci Hua" describes the scene of Wu Yueniang, Meng Yulou, Pan Jinlian, Li Ping 'er and others swinging on swings in the garden, and quotes the "Swing Poem" which is said to have been written by Tang Bohu. The poem goes:

Two young and charming girls are playing on swings in the shade of green willows. Two pairs of jade wrists are linked again and again, and four golden lotus flowers are upside down. The red powder faces the red powder face, and the crispy shoulder faces the crispy shoulder. The young master of Spring Outing whipped his fingers far away, and a pair flew down to the ninth heaven.

Li Qingzhao also composed a poem titled "Dian Jiangchun: Cuba Swing". For a while, swinging on a swing almost became the exclusive domain of women.

It was probably after the Tang and Song Dynasties that, with the development of urban economies and the emergence of a large number of citizens, swinging on a swing evolved into a carnival program in the square during festivals. Du Fu once wrote in a poem: "After ten years of playing Cuju, the young are far away; after ten thousand miles, the custom of swinging on the swing remains the same." Liu Yuxi also said, "The swing competes for order, pulling the concealed colorful rope diagonally." It can be seen that the custom of swinging on swings has spread widely and vigorously.

The Song Dynasty poet-monk Hui Hong also wrote a poem titled "Swing" :

The easel is double-cut with a verdant curve, and a beautiful lady plays in front of the small pavilion in spring. The blood-red dress flutters on the ground, sending Yurong to the heavens. Flowers moisten the red apricot rain, and colorful ropes slant the green poplar smoke. He stood calmly in his spare time, as if he were a celestial being banished from the Moon Palace.

From the above poems describing the custom of swinging on swings, we can catch a glimpse of the universality of this custom at that time. Perhaps people are tired of the traditional swing and are seeking new tricks, and the custom of the swing is beginning to change.

Zheng Banqiao of the Qing Dynasty composed poems about "swings" and kites

During the Qing Dynasty, Zheng Banqiao, the magistrate of Weixian County (now Weifang City, Shandong Province), once composed a poem depicting the joyous scenes of folk activities such as "swinging on swings" and "flying kites" in March: "Paper flowers fly like snow all over the sky, and delicate girls swing around." The five-colored silk dress sways in the wind, hoping to lure the butterflies back to spring.

Swing

- Monk Huihong

The easel is double-cut with a verdant curve, and a beautiful lady plays in front of the small pavilion in spring.

The blood-red dress flutters on the ground, sending the beauty of Yurong to the heavens.

The flower board is moistened with the red apricot rain, and the colorful rope is slanted with the green poplar smoke.

He stood calmly in his spare time, as if he were a celestial being banished from the Moon Palace.

7. Sports

In 1991, the National Minority Sports Games included "swinging on a swing" as a performance event, and later, "hanging in the autumn" was added as a competition event.

The swing, a folk activity with a history of several thousand years, still maintains vigorous vitality to this day. It enlivens people's lives and also provides folk workers with specimens rich in content.

Swing is a kind of sport created by ethnic minorities in northern China in ancient times. It was introduced to the Central Plains during the Spring and Autumn Period (770 BC - 476 BC). Due to its simple equipment and easy learning, it was deeply loved by people and soon became popular in various places. After the Han Dynasty (206 BC - 220 BC), swings gradually became a folk sports activity carried out during festivals such as the Qingming Festival and the Dragon Boat Festival, and have been passed down to this day. After the founding of the People's Republic of China, with the rise of various modern sports, swing sports have become a special activity for children in most parts of China, except for a few areas where they are still widely popular. In February 1986, the Sports Commission formulated the "Swing Competition Rules" (draft). In the same year, the swing was listed as an official event in the National Minority Sports Games. By the 6th National Games of Ethnic Minorities in 1999, the swing had developed into a larger event consisting of six individual events.

The swing competition regulations stipulate that only women are allowed to participate. It is divided into individual, double and team events. The events are divided into height competition and bell touch competition. In height competitions, the score is calculated based on the highest point reached within the prescribed number of test swings. In bell touch competitions, the score is determined by the number of times an athlete touches the bell within the prescribed height and time. The competition venue is a rectangular flat ground of 20 by 8 meters. The swing frame is 12 meters high and the starting platform is 1.3 meters high. In the height competition, each athlete has six chances to test the swing, while in the bell touch competition, they are only allowed one chance.

Swing sports are not only exciting competitive activities, but also can strengthen one's willpower and cultivate a spirit of bravery. At the same time, it is also very beneficial to the healthy development of human physiological functions.

8 Energy Swing

On May 12, 2012, in the Energy Park of the Yeosu World Expo in South Korea, the "Energy Swing" in the park could convert the swinging action into energy. While tourists were swinging and resting, the music box at the top of the swing could play beautiful music.

3. Teacher's summary: Have a preliminary understanding of what inertia is?
When we are in a car, if the car brakes suddenly, our body will lean forward, while if it starts suddenly, our body will lean backward. This phenomenon is called inertia. When swinging on a swing, we don't need to push it, but it can still swing back and forth. This is also inertia. Isn't inertia interesting? Today, let's have some fun and find out where the interesting inertia is hidden?
(3) Children freely form groups and choose various materials to discover the phenomenon of inertia.
Teacher: I have prepared some materials for you (making tops and rotating paper plates, playing with yo-yos and scooters, setting up dominoes, flipping poker cards, operating toy cars, etc.). Please try them out by yourselves, play with them and find out where the inertia is.
2. Teachers guide children to discover and feel, and encourage them to use all their senses to find answers.
3. Children communicate with each other.
Teacher: Where is the inertia you have discovered? Talk to your companion about it.
Encourage young children to boldly share their discoveries and ideas with their peers in a more coherent language.
(4) Experience and perceive inertia through playing games, and be able to express one's discoveries and feelings in relatively coherent language.
1. With questions in mind, re-select materials to discover and experience inertia.
Teacher: Please, children, choose the materials you haven't played with before and then discover where the inertia lies?
(2) Teacher-child interaction: Encourage children to boldly display or describe their achievements.
2. The teacher summarizes the principle of inertia and answers the difficult questions discovered by the children.
3. Encourage children to talk about the inertial phenomena they find in their daily lives and exchange with each other the shortcomings brought about by inertia.
Extended activities
By seeking out inertia in life, we can further understand the secrets and principles of inertia.
1. Teachers and children jointly search for large equipment around the playground that utilizes the principle of inertia.
2. Play freely and experience the joy brought by inertia.
